| Summary | 0000623: No Wireless: Broadcom BCM43142 with 3.10.0-327.4.4.el7.x86_64 kernel | ||||
| Description | I have installed centOS 7 two weeks ago and even following http://elrepo.org/tiki/wl-kmod (and many other solutions) and I don't have wireless connection (only ethernet). Has anyone have this problem with that Broadcom device? I also try to enable the touchpad but failed and I got no other option to use an external one; pnp fails at booting. | ||||

The most common kmod-wl issue is the need to build kmod-wl against a kernel within the current EL point release, which in the case for EL 7.2 would be 3.10.0-327*el7.x86_64. Please run: # find -L /lib/modules -type f -name wl.ko The output will identify which kernel (kversion) kmod-wl was built against (/lib/modules/<kversion>/extra/wl/wl.ko) and which kernels it can weak link to (/lib/modules/<kversion>/weak-updates/wl/wl.ko). The touchpad question is unrelated and not addressed here. You could look at our FAQ #4 ( http://elrepo.org/tiki/FAQ ) as a starting point. Please note that bug trackers are intended for resolving problems with packages and not for general troubleshooting. From a working kmod-wl system: # uname -r 3.10.0-327.3.1.el7.x86_64 # rpm -q kmod-wl kmod-wl-6_30_223_271-2.el7.local.x86_64 # lspci -nn|grep Broadcom 03:00.0 Network controller [0280]: Broadcom Corporation BCM4321 802.11a/b/g/n [14e4:4328] (rev 03) # find -L /lib/modules -type f -name wl.ko /lib/modules/3.10.0-327.el7.x86_64/extra/wl/wl.ko /lib/modules/3.10.0-327.3.1.el7.x86_64/weak-updates/wl/wl.ko # iwconfig wlp3s0 wlp3s0 IEEE 802.11abg ESSID:"guest" Mode:Managed Frequency:2.447 GHz Access Point: 06:18:E7:DD:52:3A Bit Rate=78 Mb/s Tx-Power=200 dBm Retry short limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=41/70 Signal level=-69 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 |

Thanks for your answer and sorry for this late one: Output of # find -L /lib/modules -type f -name wl.ko: /lib/modules/3.10.0-327.4.4.el7.x86_64/kernel/drivers/net/wireless/wl.ko but I had an 'warning' at the momento of building about incompatible wl.ko with this kernel (I can't make that it appears again due to my many tries of fixing this) the output of rpm -q kmod-wl: package kmod-wl is not installed and # lspci -nn|grep Broadcom 06:00.0 Network controller [0280]: Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01) no wireless extension on iwconfig |

Your issues are unrelated to kmod-wl, because kmod-wl is not installed. Also, there is no native EL7 .../kernel/drivers/net/wireless/wl.ko. My assumption is that your wl.ko is due to manually building the Broadcom driver, which will fail for EL7 kernels because the kernel version does not reflect the kernel wireless stack due to RHEL backporting. The wl-kmod.nosrc.rpm corrects that issue and allows a functional kmod-wl / wl.ko to be built for EL5/6/7. Please follow the instructions at http://elrepo.org/tiki/wl-kmod and then install the resulting kmod-wl. If you need additional help, please subscribe to our mail list ( http://lists.elrepo.org/mailman/listinfo/elrepo ) where many members are experienced with kmod-wl usage. |
